简要总结

This study focuses on menthol (n = 125) and non-menthol (n = 125) smoking young adults (YAs; defined here as ages 18 to 26).

详细描述

The study will occur in three phases.

In session 1 of Phase 1, participants will engage in ad libitum smoking session of one's preferred cigarette brand (menthol or non-menthol). In session 2, participants will take several puffs each of a commercially available menthol and non-menthol cigarette (i.e., Camel Crush) and complete a complete a series of pre-post smoking questionnaires, and in Session 3 participants will complete a computerized task to measure perceptions of cigarette smoking. For the computerized task, participants will be able to "win" points toward earning puffs of a cigarette and will be able to smoke puffs earned. Participants will be asked to abstain from smoking for at least 12 hours before each in-person visit.

Phase 2 participants will engage in 14 days of surveys they will complete on their cell to measure different aspects of smoking behavior. These surveys will happen twice a day at random times.

For phase 3, participants will complete an assessment of smoking behavior and related factors 6-months after the baseline assessment either in-person, in the laboratory, or via telephone or online (if in-person follow-up is not viable).

The order in which phases occur differed was a result of COVID-19 restrictions on data collection. For some participants, they started EMA first and then began laboratory data collection when in-person was allowed. For others, they started laboratory data collection when COVID restrictions were lifted. Thus, the participant flow may appear unbalanced.

结局指标

主要结局

Subjective Response to Smoking Cigarettes From the Cigarette Evaluation Scale

时间窗: immediately after smoking usual brand cigarette, at baseline

ratings of subjective satisfaction from smoking cigarettes, 1= not at all to 7 = extremely. Higher scores indicate greater positive subjective response. The minimum score is 1and the maximum score is 7.

Average Daily Subjective Response From Smoking

时间窗: Phase 2 daily diary surveys (estimated 2-4 weeks after baseline)

average daily scores of subjective reward from smoking from daily diary surveys, 1= not at all to 7 = extremely. Higher scores indicate greater positive subjective response. Averaged across 14 days.

Highest Trial Competed for a Menthol Cigarette Puff in the Choice Task (Relative Reinforcing Value for Menthol Cigarettes)

时间窗: Lab session 3 (estimated average 1-4 weeks after baseline)

Participants completed a choice task assessing willingness to "work" to click targets on a computer screen to earn menthol or non-menthol cigarette puffs. The relative reinforcing value for menthol was defined by the Breakpoint, or the highest trial (out of 10 trials) completed for a menthol cigarette puff.

Past 30-day Cigarette Smoking Frequency

时间窗: 6-month follow-up survey (6-months post-baseline)

Number of days smoked cigarettes in the past 30-days

Puff Topography

时间窗: Laboratory session 1 (up to 4 weeks after baseline)

Number of cigarette puffs after smoking one's preferred brand/flavor during lab session 1, Phase 1.

次要结局

  • Number of Clicks for Menthol Cigarette Puffs on the Behavioral Choice Task(immediately after completing the behavioral economic choice task, lab session 3 (estimated average 1-4 weeks after baseline))
  • Quantity of Past 30-day Tobacco Product Use(6-month follow-up (6-months post-baseline))
  • Number of Participants With Intentions to Smoke Menthol Cigarettes(6-month follow-up (6-months post-baseline))
  • Cigarettes Per Day(Phase 2 daily diary surveys (estimated 2-4 weeks after baseline))
  • Average Daily Craving From Smoking(Phase 2 daily diary surveys (estimated 2-4 weeks after baseline))
